Abstract (en)

[origin: WO9905787A1] A digital mode receiver for the reception of signals from multiple independent subscribers, as on a cable television bidirection broadband data transmission system, adapted for subscriber inquiries and two way data transmission. Each burst (fig. 2) comprises a fixed preamble portion and a variable data portion. The received burst is sampled and fed to a sample storage buffer (4). The preamble portion's output is used to initialize an equalizer (6), and to synchronize carrier and modulation clock. By repeating the processing of the preamble and optionally all or part of each burst, accuracy of detection of the variable data is improved, so that it is feasible to receive individual burst without burst to burst coordination, while using a short preamble for increased efficiency.
